Sourcing cast steel crusher liners from China

Zero duty if the liner falls within this heading

Read from the UK Trade Tariff on 19 October 2026, heading 7325 covers other cast articles of iron or steel. For cast steel liners accepted under this heading, the supplied line is 7325 99 90 90. The table repeats that candidate line for different liner applications; it does not establish their classification.

The supplied snapshot shows 0% duty for goods from China on this steel line, with no anti-dumping or countervailing duty, suspension, steel measure or attached import control listed. The anti-dumping measure elsewhere in this heading concerns specified cast iron ground-system covers, rather than this steel line. See the wider castings guide.

Ask your customs broker to review the drawing, material, machining and intended crusher application before accepting this code. Use our commodity code guide to prepare the classification enquiry.

Specify the alloy, wear profile and mounting fit

Give the foundry the crusher model, part reference and approved drawing revision. Specify alloy chemistry, heat treatment, hardness acceptance criteria, wear-face profile, backing face, bolt holes and seating surfaces. Describe the feed material and operating conditions so the foundry can explain its proposed alloy rather than merely quote a compatible part.

Agree material testing, casting defect acceptance and any repair welding before production. Ask for heat-linked chemistry results and heat-treatment records. For resale, keep the part reference, application limits and batch identity with the goods. Businesses that own, operate or control work equipment have duties under the work equipment regulations.

Worked duty example

Illustrative example, not a quote: 500 small cast steel crusher liners, illustrative order only under 7325 99 90 90, invoiced at £30,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £34,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £34,000, so it is £6,800. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. The import duty and VAT guide explains each step.

Inspection checklist

Material: match casting heat marks to chemistry reports and heat-treatment records; compare hardness results with the agreed acceptance criteria.

Fit: measure bolt holes, seating faces, liner thickness and wear profile against the approved drawing; trial-fit a sample using the agreed fixture.

Soundness: inspect for cracks, shrinkage, porosity and unapproved weld repairs; use the agreed non-destructive examination method on critical areas.

Arrival: check casting identity, transport damage and support points before release to stock. Keep photographs and measurement records through quality inspection.

What goes wrong

A familiar part reference can hide a different wear profile or mounting arrangement. Incorrect alloy chemistry or heat treatment can produce rapid wear or cracking; distorted seating faces can prevent proper support. A hardness result alone does not establish casting soundness or service suitability.

Resolve discrepancies before fitting rather than grinding or welding the liner to make it fit. HSE guidance says maintenance needs to be correctly planned and carried out. Plan replacement work around the crusher manufacturer's instructions, including handling the liner and checking its seating.
